Every european country was once an empire cuz, they conquered other countries and had colonies. I would say Norway, Norway is 2th best in the european military, russia is 1st becouse they have more recruits and officers than us. (I'm Norwegian) Also, every country has great city. Still, Norway is richer than UK, Norway is actually the 2th richest country in the world, then comes America. We always buy the newest things in technology.
(We got a lot of oil and tons of Norwegian fish we sell to America, UK, spain, etc.)
I'm not saying this, just to brag. But, it's true.
Norway has a lot of fjords, cliffs and mountains, worth seeing. Like trolltunga, prekestolen, for example.
That is just a bit of the nature.
Heres a lot more to do in Norway:
